PATENT EDWARD BOURNE, OF ALLEGHENY, PENNSYLVANIA.

WASHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,849, dated December 28, 1880.

Application filed May 4, 1880.

To all whom it may concern Be it known that I, EDWARD BOURNE, of Allegheny, in the county of Allegheny and State ofPennsylvania, have invented anew and useful Improvement in Washinglviachines; and I do hereby-declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in washing-machines; and it consists of a tub provided with a perforated, corrugated, detachable, and cushioned bottom, combined with a novel constructed pounding-disk, to which is imparted a vertical and rotating motion, all as will be hereinafter fully described.

To enable others skilled in" the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation.

In the accompanying drawings, which form part of my specication, Figures l and 2 represent side elevations of my improvement in washing-machines. Fig. 3 is a vertical section of the same. Fig. 4L is a face view of the pounding-disk. Fig. 5 is a face view of the perforated, corrugated, detachable, and cushioned bottom.

In the accompanying drawings, A represents the tub, which is mounted upon legs B and provided with a lid, C, which is hinged at D and held down on the tub by a latch, E.

In the center of the bottom F of the tub A is secured, by a screw-nut, g, iixed to the bot torn of the tub, a cylinder, h, in which is placed a spiral spring, z', on the upper end of which rests the hollow center pin, j, of the perforated, corrugated, and detachable bottom k, having ribs or corrugations, as at l, and perforations, as'at m. (Shown in Fig. 5.) The lower end of the cylinder h is provided with a valve, n, for drawing off the water from the tub A, which water flows into the cylinder through an opening or openings, o, in said cylinder at the bottom of the tub, as shown in Fig. 3.

The poundingdisk p (represented in Figs. 3 and 4) has three openings, q, passing through it, and has three corrugated pounding-surfaces, r, the corrugations s of which are arranged obliquely to the axis of said pounding-disk.

(No model.)

To the upper surface of the pounding-disk p is attached a sha-ft, t, which passes through an opening in the center of the lid, and is provided with an adjustable lift-piece, u, held in a tixedtposition on the shaft t by means of a thumb or set screw, c.

To the lid G is secured the journal-bearing w of the crank-shaft 50,011 the inner end of which is an S-shaped eccentric, y.

The skillful mechanic, from the foregoing dcscription and reference to the accompanying drawings, will readily understand the construction of the several parts and the relation they bear to each other. I will therefore proceed to describe the operation, which is as follows:

The clothes to bewash ed having been soaped and soaked in suds in the usual manner, and the tub A having been supplied with a suitable quantity of water or suds, the lid (l is raised up and turned back, the clothes :are removed from the soak, passed through a wringer or wrung ont by hand, and placed in the tub A. The lid C is then turned down and secured by the latch E, as shown in Fig. 2. The operator then turnsv the crank a, which will revolve the crank-shaft x, which will revolve the eccentric y, the curved points b of which, coming in contact with the lift-piece a, will raise up the pounding-disk p, causing it to be lifted with a rotary motion, which, combined with the openings g in the said pounding-disk and the spring of the cushioned bottom k, will turn the clothes in the act of lifting said disk. The eccentric y, having lifted the pounding-disk p, passes from under the lift-piece a, allowing the pounding-disk to drop with the force and speed of its own gravity upon the clothes in the tub A. The perforated,corrugated, cushioned, and detachable bottom yields to the downward force of the pounding-disk, but

rebounds with an upward force, which, com

IOO

pounding-disk p the bottom 7c yields, thereby forcing the suds up through the openings m into the clothes, which greatly facilitates the Washing process.

After the clothes have been subjected sufficiently to the action Of the pounding-disk p and cushioned bottom lc, they are removed from the tub A and treated in the usual way of boiling, rinsing, wringing, and drying.

Having thus described my improvement, what I claim as of my invention isl. In a washing-machine, the combination of the perforated, corrugated, detachable, and cushioned bottom and the vertically and rotarily moving pounding-disk, having openings
